After I updated to IOS 8.4, I can't update Keynote, Numbers and Pages. Says Download corrupt. I have updated other Apps however including GarageBand

After I updated my iPhone 6, 64GB, to IOS 8.4, I received notice that I needed to update GarageBand, Keynote, Numbers and Pages. When I did an Update all it updated GarageBand but said it couldn't update Numbers and two others (based on updates identified these were Pages and Keynote). The message says Download corrupt. I tried the retry several times and got the same result.
